Nicks' name and music has been referenced often since the "Coven" chapter began last month. The character Misty Day, played by Lily Rabe, is obsessed with the singer who, in real life, has had to shake longheld rumors linking her to witchcraft.

According to "Entertainment Weekly," Nicks was reportedly reluctant to appear on the show at first due to the rumors but Murphy, a longtime fan of Nicks, persuaded her to do it after explaining the part, which has yet to be divulged.

It's also not yet known when Nicks will appear on the show. "American Horror Story: Coven" airs Wednesdays at 10:00 pm Eastern on FX. The show was recently renewed for a fourth season.
